    @jetnoise Wind wasn't bad, in one case maybe 6kt with only a light side component and mostly headwind. Control is with pedals. As I accelerate the plane down the runway (way too fast), I'll eventually feel that it wants to yaw off to the side, and even a very slight correction will send it careening off the opposite way. The pedals aren't set up with an extreme curve or anything and work smoothly otherwise, it's just that moment in the life of an 850 that gets exciting.

    With essentially a 3-position selector, the low idle position could easily take the middle 90% of the axis, and only 0-5% would be cutoff and 95-100% as high idle. That would make it much easier to hit, and it's not like in the Kodiak where you need to torque in the air condition in low idle :-D

    Great response, it's already a fantastic aircraft in my opinion, so I'm excited to see how it develops - thanks to Black Square for his hard work so far

    Thank you "usul" and "pedwards"
    I had assignments to pitot tubes on both the keyboard and Honeycomb Bravo.
    I deleted them both.
    I fly exclusively in VR, and I try to have all assignments deleted to be able to manipulate buttons/switches/rotaries with the mouse.
    Thanks again!
    Regards,
    Roberto

  • CWS yoke button / EADI mode

    CWS is not a function of GPS unit, it's a function of autopilot. In our case - KFC325 unit. Here is the screen from the docs for 700/850 version (from here) . Moreoover, when I press CWS button on the yoke, EADI correctly indicates it with white "CWS" annunciators, but apparently it just has no effect on AP afterwards (and even when CWS is pushed in, the AP is still actively flying the plane)

    @jetpro same thing happened to me, just unbind hardware like bravo throttle etc. from pitot and in my case avionics master on/off to fix the problem

    @rbringh looking at a PIM/POH/whatever, it looks like RPM is only really changed during run-up to exercise the prop, and during cruise to reduce noise at mostly negligible impact on all other parameters. As long as you change Np slowly, it doesn't have a large impact on overall torque in the sim, but quick changes will do something. There's also a torque limiter at work when you aren't in 850 Mode that makes everything but torque regulate to remain safe, and in 850 Mode where the limiter is inactive, I really don't know what's even going on.

    A footnote on Np in a performance table (all tables are made for 2000 RPM...):

    Propeller RPM utilization between 1600 and 2000 RPM is possible without changing performance. Display the TRQ indicated in table with Np = 2000 RPM, then reduce Np without exceeding 121.4 % TRQ.

    That pretty much looks a bit like leaning, but for noise, and some Socata Magic.

    @eker
    Watching both the Justflight info video, and 737ng driver detailed test flight, there is no restriction in low prop rpm area.
    Without gates in our hardware throttles, I am glad BS simplified the beta range, in ground fine pitch (in air) you certainly hit the wall and drop out of the sky. Excellent decision by the developers..
